What happens physically when the user interacts with the computer, when a button is pressed on the keyboard for example?

Question

The question is the basics of how a computer works, most people seem to think it is magic or something, I would like to understand.

Is it an electric charge that goes on a chip? how does that translate into a screen?

Answer 1

Each key floats over a pressure pad. When the key is pressed, the pad is activated and an electrical signal gets sent to the motherboard (operating system) that the letter is being pressed. The motherboard processes the data, then sends a signal to the monitor, effectively making the letter appear on the screen relative to what key you pressed. That’s how I understand it at least.
